The Science of Everything Podcast

A discussion of the basic concepts of magnetism, including magnetic fields, magnetic poles, and electromagnets. I also discuss the ultimate subatomic source of magnetic force in the phenomenon of electric spin, and explain how this leads to the different types of magnetic materials: ferromagnets, paramagnets, and diamagnets. I conclude with some applications of electromagnetism, including electric generators and motors, transformers, and a brief discussion of Maxwell's equations. Recommended prelistening is Episode 43: Electric Forces and Fields.

An analysis of memory, including a discussion of the different types of memory, the capacity of short term memory, how environment and depth of processing influences learning and recall, the relationship between memory and familiarity, and different types of amnesia. Complements Episode 20: The Reliability of Memory.

A analysis of the sense of smell, beginning with the nose, the olfactory epithelium and the different types of receptor proteins, and progressing through the processes of sensory transduction, transmission of neural signals to the olfactory bulb, and thence into the higher regions of the brain. I also discuss the sense of smell in humans compared to that of other animals, with a focus on the special abilities of bloodhounds. Recommended prerequisite is Episode 38: Neurons and Synapses.

A discussion of how our sense of taste works, including an overview of the basic anatomy of the tongue and relevant brain circuits, a discussion of taste buds and how they work, a review of the five basic tastes and how they differ, and a look at some other interesting topics such as pungency and aftertaste. Recommended pre-listening is Episode 10: The Cell and Episode 38: Neurons and Synapses.

We begin with a discussion of basic electrical phenomena such as current, voltage, resistance and power, before applying these ideas to the analysis of circuits, including series and parallel circuits. We then apply these concepts to understand a number of interesting phenomena, including light bulbs, lightning, and why electricity can be dangerous. Recommended pre-listening is Episode 43: Electric Forces and Fields.

A discussion of the notion of trade and exchange, including the purpose of these activities, the gains from trade, and the role of comparative advantage. I also examine some recent trends in global trade, and briefly discuss some of the major global trade institutions such as the WTO and World Bank and their role in attempting to reduce trade barriers. The episode concludes with a brief discussion of the concept of 'Buy Local'. Recommended pre-listening is Episode 12: The Price System.
